This appears to be a very easy and effective attack on election systems that does not even involve trying to flip votes.
"The center also distributes the voter registration list to counties for use on their ExpressPoll pollbooks; if attackers were to delete voter names from the database stored on the center’s server or alter the precinct where voters are assigned, they could create chaos on Election Day and possibly prevent voters from casting ballots. This is not an idle concern: During the presidential election last year, some voters in Georgia’s Fulton County complained that they arrived to polls and were told they were at the wrong precinct. When they went to the precinct where they were redirected, they were told to return to the original precinct. The problem was apparently a glitch in the ExpressPoll software."
